Question 15

If 9@7=4; 6@1=10; 7@4=6; then what is the value of 8@2=?

Solution

The positive difference of the number is multiplied by 2.

Eg = 9@7 = $$(9-7)\times2=2\times2=4$$

and 6@1 = $$6-1)\times2=5\times2=10$$

and 7@4 = $$(7-4)\times2=3\times2=6$$

Similarly, 8@2 = $$(8-2)\times2=6\times2=12$$

=> Ans - (D)
